Tungsten electrodes for TIG welding
Every perfect weld seam requires precision, control and the right tool the right tool. Discover our range of tungsten electrodes, the centrepiece of every TIG welding process. They are not just a component, but the tool for a stable arc and a clean a stable arc and a clean welded joint. With the right tungsten electrode from our shop, you can easily achieve the quality the quality that characterises your work. You can rely on our Expertise to achieve the optimum result.
Why tungsten as an MMA electrode?
Tungsten is used as an MMA electrode for TIG welding (tungsten inert gas welding) because it has an extremely high melting point Melting point of around 3422 °C. In contrast to other MMA electrodes pure tungsten does not melt during use. This means that the Electrode tip remains stable, which enables reliable arc ignition and arc -and guidance. This is crucial for precise, clean and safe safe TIG welding work. With the right tungsten electrode you minimise the risk of contamination in the weld seam and always always achieve optimum results.
Which TIG tungsten electrode do I use for which material?
The choice of the right tungsten electrode depends on the material to be welded Material to be welded and the type of current (direct current DC or alternating current AC). The MMA electrodes are identified by international colour codes that provide Colour codes that provide information about their alloy and area of application.

Colour code table:
| Colour code | Alloy | Main application |
| Green (WP) | Pure tungsten | Ideal for AC applications (aluminium, magnesium, aluminium alloys). Provides a stable arc. |
| Gold (WL15) | 1.5 % lanthanum oxide | Universal electrode for AC and DC applications. Excellent ignition properties, good service life. Suitable for unalloyed steel, stainless steel, aluminium and titanium. |
| Blue (WL20) | 2.0 % lanthanum oxide | One of the most frequently used MMAs. Ideal for DC applications (unalloyed steel, stainless steel, copper) and for AC applications with inverter welding equipment. |
| Pink (W + Pink) | Non-radioactive mixture | Non-radioactive alternative to the red WT20 MMA. Mostly for DC applications (steel, stainless steel, copper). |
| Pink-grey (LymoxLux) | Special mixture | Universal electrode for AC and DC applications, often marketed as an alternative to the blue or green MMA. |
| Grey (WC20) | 2.0 % cerium oxide | Universal MMA, similar to lanthanum electrodes. Works well in AC and DC applications and has optimum starting properties, especially at low currents. |
| Black (WL10) | 1.0 % lanthanum oxide | Universal electrode with good ignition properties, suitable for AC and DC. |
| Turquoise (WR2) | 0.2 % zirconium oxide | Alternative to the thorium MMAs. Mainly for AC applications (aluminium, magnesium) and for welding with higher amperage. |
| Red (WT20) | 2.0 % thorium oxide | Standard for DC applications (steel, stainless steel, copper). Thorium is slightly radioactive, which is why this MMA is used less frequently. |
| Orange (WT40) | 4.0 % thorium oxide | Standard for DC applications at higher currents. |
| White (WZ8) | 0.8 % zirconium oxide | Especially for AC applications (aluminium, magnesium). Provides very stable ball formation and a smooth arc. |
How do I choose the diameter of the tungsten electrode?
The diameter of the tungsten electrode must always be adapted to the welding current (amperes) and the type of current (DC or AC). The most common Standard sizes are 1.6 mm, 2.4 mm and 3.2 mm. A diameter that is too thin Diameter can lead to overheating, while a diameter that is too thick Diameter can produce an unstable arc.

Which tungsten electrode is best suited for beginners?
For beginners, we recommend universally applicable MMAs that are are not radioactive and are suitable for different materials and Types of current. The best choice here are the lanthanum MMAs (WL15 in gold and WL20 in blue) or the cerium electrodes (WC20 in grey ) Grey). They offer good arc stability, are easy to ignite and are and can be used for both DC and AC applications. With these MMA electrodes, you can optimally learn the basics of TIG welding optimally.
